    The expression k & 1 is evaluated first.

    & is a bitwise AND operator, so this will yield 1 if the least significant bit in k is set, 0 otherwise.

    The result of the expression is then evaluated. If it is 0, then the if condition is false. If it is any other value, the if condition is true.

    an if statement does not need a logical operator.

    It just looks for zero or non zero. Logical operators produce 1 or 0 depending if the expression is true of false..

    printf("%d %d",k&1,k==1);
